FYI: I think this thread has drawn so many downvotes due to there being so many of these threads already existing. Nice list shash, but I think you also posted it in another similar thread recently. These threads have a tendency to attract lots of noob posts shouting w3schools or spammers linking to their own sites or worse. May I kindly request that any further posts ONLY supply quality links not already mentioned in the list above. Thank you.
